O Change History

Changes relative to the previous public Working Draft of SVG Tiny 1.2 are described below. Many of these changes were made in response to LastCall feedback.

O General Changes

• Attributes with boolean values have been changed to use enumerations, to allow extensibility.

O Coordinate Systems, Transformations and Units (coords.html)

• Elements that establish new viewports are now: svg, animation, image, video. Clarified that foreignObject does not establish a viewport.
• The intrinsic aspect ratio of SVG content has been defined.
• No support for % on ObjectBoundingBoxes

O Linking (linking.html)

• ID references use XPointer Framework Shorthand Pointers.
• The specification now uses IRIs rather than "URIs or a string which may be converted to a URI as specified".

O Animation (animate.html)

• The behaviour of 'paced' animation has been clarified.
• The behaviour of animateTransform has been clarified.
• 'wallclock' remove as it was complex, rarely used, and hard to implement correctly.

O Document Structure (struct.html)

• The page and pageSet elements have been remvoed from SVG Tiny 1.2.
• Added discard element and playbackOrder attribute.
• Removed streamedContents attribute.
• The use element can now reference external content with some restrictions.
• The image element can no longer reference SVG content. The animation element should be used instead.
• The opacity property has been added to the image element.
• The switch element has increased availability.
• requiredFormats, requiredFonts, requiredFeatures and requiredExtensions are now specifically allowed in SVG Tiny.
• The overflow attribute is now available on use. The only valid value is 'visible'.

O Text (text.html)

• The textArea and associated elements replace the previous Flowing Text features.
• 'editable' is now allowed on text elements with children, but the children are flattened when editing occurs

O MultiMedia (multimedia.html)

• The animation element has been added to the specification.(external use/images)
• The overlay attribute was added to the video element.
• The transformBehaviour attribute was added to the video element.
• The audio-level property has been extended to container elements as well as media elements.
• The addition of run-time synchronisation attributes to audio, video and animation.

O Interactivity (interact.html)

• The focusNext and focusPrev attributes have been added in preference to navIndex.
• 8-way navigation is now allowed through the focusNorth, focusNorthEast, etc... attributes.
• The capture phase is no longer supported in SVG Tiny 1.2.

O Painting: Filling, Stroking, Colors and Paint Servers (painting.html)

• viewport-fill and viewport-fill-opacity replace background-fill and background-opacity.

O Scripting (script.html)

• The application/ecmascript Internet Media Type for ecmascript is now specified in the scripting chapter. Use of the older, non-registered text/ecmascript Internet Media Type is deprecated.
• The type attribute (on script and handler) is now optional and defaults to value of contentScriptType.

O uDOM (svgudom.html)

• A focus API has been added for programatic modification of focus.
• fonts and animations cannot be modified by scripting once inserted.
• EventListenerInitializer2 inteface was added to the uDOM.
• The SVGElementInstance interface was added.
• '#text' is used to access the text content of a test node. The textContent attribute on the Node interface is another way to access this information.
• The ownerDocument attribute was added to the Node interface.
• The textContent attribute was added to the Node interface.
• The SVGVisualMediaElement interface was added.
• The ElementTimeControl interface was enhanced.
• GetAttributeNS was introduced and applies to any attribute on a non-svg element, any namespaced attribute on a non-svg element, and all the attributes in the trait table.
• createElementNS can now create all elements in the SVG namespace.
• getAttribute/getAttributeNS are now available in the uDOM, but have restrictions when used with elements from the SVG namespace.
• setAttributeNS is also available in SVG 1.2 Tiny.
• removeChild now removes elements with and without id's (earlier only without).
• Trait table has been extended.

O Implementation Requirements (implnote.html)

• The error handling defined in the specification has been modified better support extensibility and versioning.
